Hunt, Jr., Governor Jonathan B. Howes, Secretary William L. Meyer, Director April 9, 1997 To: Warren County Working Group, AVA DEHNR From: RE: Joel Hirschom, Patrick Barnes, Science Advisors Ed Mussier, Solid Waste Section, Division of Waste Managemen~ Geotechnical Test Results on Landfill Soils V Attached please find a copy of the laboratory geotechnical test results. Soil samples were obtained with shelby tubes of the protective cover, landfill cap, and approximately two foot intervals within the landfill. Index and classification tests were run on all samples and permeability tests were run on a sample of the protective cover, one sample of the clay barrier layer from each borehole, and two samples within each borehole. Eighteen samples for moisture content were obtained from split spoons, and analyzed. Please do not hesitate to contact the Division if you have any questions. P.O.
